Some near misses A pair of dangerously close space encounters is adding to tensions between the U.S. and China, while underscoring the potential peril to astronauts as satellite constellations and debris proliferate in orbit.

Two SpaceX satellites had near misses with China’s space station earlier this year -- one of them within 4 kilometers (2.5 miles) -- in the latest sign of dangerous overcrowding in low earth orbit. In both instances, the orbiting lab made evasive maneuvers to avoid the Starlink satellites operated by Elon Musk’s space venture. The margin for a near-miss in October could have been as little as a few hundred meters if the astronauts on board the space station hadn’t shifted to a different altitude, according to data compiled by astrophysicist Jonathan McDowell.
The close encounters prompted the Chinese government to criticize SpaceX in a Dec. 6 memo to a United Nations committee that oversees operations in space. China’s complaint could prompt global action on managing congestion in space.
China’s memo cites Starlink-1095, which had operated at an average altitude of 555 kilometers earlier this year, before descending to 382 kilometers and having a “close encounter” with the China Space Station on July 1. An incident with a separate Starlink satellite occurred Oct. 21.
The Chinese government alerted UN Secretary-General Antonio Guterres on Dec. 3, Foreign Ministry spokesman Zhao Lijian said Tuesday at a press briefing in Beijing. He contended that the U.S. isn’t meeting its obligations under the Outer Space Treaty. The incidents endangered the station’s operators, he said.

China speeds up moon base plan in space race against the US
https://www.scmp.com/news/china/science … against-us

The new aim of the Chang’e 8 moon landing mission is to set up a lunar research station by around 2027, space authority deputy director says

China’s Chang’e 8 moon landing mission originally aimed to carry out scientific experiments such as 3D printing of lunar dust, which would follow two more launches in the next few years.
But Wu Yanhua, deputy director of the China National Space Administration, said the Chang’e 8’s new job was to put an unmanned research station on the surface of the moon, previously scheduled for 2035.
Wu did not give details on the reason behind the change of plan, but stressed that the purpose of the mission was to “build a solid foundation for the peaceful use of lunar resources”.

Wu Yanhua, deputy director of the administration, said China would carry out lunar exploration in the future Chang'e-6, Chang'e-7 and Chang'e-8 missions.
As planned, Chang'e-7 probe will be launched to the south pole of the moon first. Since Chang'e-6 is a backup of Chang'e-5 sample-return mission, it will be launched after Chang'e-7 to bring back samples on the lunar south pole. Chang'e-6 mission will be followed by Chang'e-8, a step toward building a model of a lunar scientific research station.

China is hatching a plan to find Earth 2.0
https://www.nature.com/articles/d41586-022-01025-2
“Our satellite can be 10–15 times more powerful than NASA’s Kepler telescope in its sky-surveying capacity,” says Ge.

Doubling the data
NASA launched Kepler in 2009, aiming to find out how common Earth-like planets are in the Galaxy. To confirm that an exoplanet is Earth-like, astronomers need to measure the time it takes to orbit its sun. Such planets should have an orbital period similar to Earth’s and transit their suns about once a year. Chelsea Huang, an astrophysicist at the University of Southern Queensland in Toowoomba, says that scientists need at least three transits to work out a precise orbital period, which takes about three years of data, and sometimes more, if there are data gaps.
But four years into the Kepler mission, parts of the instrument failed, rendering the telescope unable to stare at one patch of the sky over an extended period of time. Kepler was on the cusp of finding some truly Earth-like planets, says Huang, who has worked with the Earth 2.0 team as a data-simulation consultant.
With Earth 2.0, astronomers could have another four years of data that, when combined with Kepler’s observations, could help to confirm which exoplanets are truly Earth-like. “I am very excited about the prospect of returning to the Kepler field,” says Christiansen, who hopes to study Earth 2.0’s data if they are made available.

https://www.spacedaily.com/reports/Chin … a_999.html

China's Tianqin-1 satellite has acquired the global gravity field data during its in-orbit operation, according to Sun Yat-sen University in south China's Guangdong Province.

The satellite was launched in December 2019 to test the technologies of the space-based gravitational wave detection program "Tianqin." The program Tianqin, meaning "harp in the sky," was initiated by the university in 2015.

The gravity field data is of great significance to the national economy and people's livelihood as the relevant data can aid geodesic survey, geophysics, oil and gas exploration, and disaster prevention and mitigation.

'Flagship Chinese space telescope to unravel cosmic mysteries'

Chinese Survey Space Telescope, also known as the Chinese Space Station Telescope (CSST) and Xuntian Space Telescope, is a space-based optical observatory for astronomers to carry out sky surveys, capturing a general map or images of the sky.
The CSST is a bus-sized facility with a length equal to that of a three-storied building. It has an aperture of two meters, a bit smaller than the Hubble Space Telescope, but its field of view is 350 times larger than Hubble in area, said Liu Jifeng, deputy director of National Astronomical Observatories Of China (NAOC), in an exclusive interview with Xinhua.
https://www.shine.cn/news/nation/2205055225/
"The field of view is the area of the sky a telescope can see at one time," said Li Ran, project scientist of the CSST Scientific Data Reduction System. Hubble's field of view is approximately one percent of the size of a fingernail at an arm's length, thereby the telescope, in its thirties, observed only a tiny fraction of the sky, Li added.

"Water may have been on Mars much more recently than scientists thought, China's rover suggests"

https://www.space.com/mars-water-more-r … hina-rover

Scientists have long believed that Mars was wet around 3 billion years ago, during the planet's Hesperian period, then lost much of its water. But the a new study presents evidence of water activity from just 700 million years ago, well into the current Amazonian period, posing a new puzzle to crack about the Red Planet and its history.

The new study is based on data from China's Zhurong rover, which is part of the Tianwen-1 mission and touched down on the surface of Mars in May 2021. In particular, the scientists used data the rover gathered during its first 92 Martian days, or sols, at its landing site in Utopia Planitia. Yang Liu, a researcher at the National Space Science Center (NSSC) under the Chinese Academy of Sciences (CAS), and colleagues analyzed data from three different instruments on Zhurong: the laser-induced breakdown spectrometer (MarSCoDe), the telescopic microimaging camera and the short-wave infrared spectrometer.

China to put large telescope in orbit next year
https://www.spacedaily.com/reports/Chin … r_999.html
China plans to launch a large space telescope next year to fly alongside the Tiangong space station, according to the China Academy of Launch Vehicle Technology.
The academy said a Long March 5B heavy-lift carrier rocket will deploy the Xuntian space telescope in a low-Earth orbit similar to the track of the Tiangong station as they both circle Earth. The telescope will carry out deep-space observation and research in the frontier fields of science, it said.

China's Wentian lab module has a length of 17.9 meters, a diameter of 4.2 meters. It duplicates the control functions of the base unit of the station. The module is equipped with an airlock, scientific equipment and a robotic arm.

The history of the Moon itself is surprising (to me at least) in the level of detail. That history is in support of the presentation of present likely value of the materials of the Moon.
